sdcard: allocate "DriveInfo" to delete the "BlockBackend" automatically

When the sdcard is detached, "virtio_blk_device_unrealize" marks
auto deletion flag to the "DriveInfo". But "qmp_marshal_input_blockdev_add"
does not create the "DriveInfo". To destroy BlockBackend object automatically
we need to create dummy "DriveInfo".
